Synthesis, electrodynamics and biosensor applications of novel sulphonated polyaniline nanocomposites
(University of the Western Cape, 2007)
The overall aim of this thesis was to prepare nanostructured more processable heteronuclear sulphonated polyanyline nanocomposites with electroconductive properties suitable for applications in biosensors. The sulphonated ...
Synthesis and electrochemical characterisation of conducting polyaniline-fly ash matrix composites
(2005)
The aim of this study was to produce useful composite materials from fly ash, a major waste product of coal combustion from power plants. Polyaniline-fly ash (PANI-FA) composites were prepared by in situ polymerisation of ...
Low temperature tungsten trioxide nano/micro-systems for applications in gas sensing and electrochromism
(2013)
In this work we primarily set out to investigate the technique of Aqueous Chemical Growth as a means of producing WO3 thin films that find applications in gas sensing and electrochromism. For the first time we demonstrated ...
Towards rapid electrochemical test system of polyanilino-laccase-on-gold enzyme nanobiosensor for water estrogens
(2013)
Current water treatment technologies do not remove many endocrine disruptor compounds (EDCs) such as 17α-ethynylestradiol (EE2) in its entirety, and the amount of these pollutants that continues to enter the aquatic ...
Electrochemical immunosensor based on cyclodextrin supramolecular interactions for the detection of human chorionic gonadotropin
(University of the Western Cape, 2012)
Glucose oxidase (GOx) and horseradish peroxidase (HRP) are important enzymes for the development of amperometric enzyme linked immunosensors. The selectivity of each enzyme towards its analyte deepens its importance in ...
Synthesis of sulphonated and transition metal oxide doped polymeric nanocomposites for application in design of supercapacitors
(University of the Western Cape, 2011)
To meet a fast-growing market demand for next generation portable electronic devices with higher performance and increased device functionalities, efficient electrical energy devices with substantially higher energy, power ...
The design of ultrasensitive immunosensors based on a new multi-signal amplification gold nanoparticles-dotted 4-nitrophenylazo functionalised graphene sensing platform for the determination of deoxynivalenol
(University of Western Cape, 2014)
A highly dispersive gold nanoparticle-dotted 4-nitrophenylazo functionalised graphene
nanocomposite (AuNp/G/PhNO2) was successfully synthesised and applied in enhancing
sensing platform signals. Three label-free ...
Nanocomposite immunosensor for anti-transglutaminase antibody
(University of the Western Cape, 2009)
Coeliac disease (CD) is a gluten intolerance condition that results in the flattening of the villi, which line the bowel. It is the most common cause of malabsorption of food nutrients. This inability to absorb sufficient ...
The Isolation and Electrochemical Studies of Flavanoids from Galenia africana and Elytropapus rhinocerotis from the North Western Cape
(University of the Western Cape, 2010)
In this study two medicinal plant species, namely Galenia africana and Elytropapus rhinocerotis, the former belonging to the family Aizoceae and the latter belonging to the family Asteraceae, have been investigated and ...
Synthesis and electrochemistry of novel conducting dendrimeric star copolymers on poly(propylene imine) dendrimer
(University of the Western Cape, 2011)
One of the most powerful aspects of conducting polymers is their ability to be nanostructured through innovative, synthetically manipulated, transformations, such as to tailor-make the polymers for specialized applications. ...
